NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 333.580, datedJanuary 5, 1886.

Application filed November 2, 1885. Serial No. 181,579. (NO model.)

To all whom it may concern:

Be it known that I, GEORGE W. WHITE a citizen of the United States, residing at Belle Mina, in the county of Limestone and State of Alabama, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to nut-locks designed for use in connection with the nuts or burrs of bolts employed to hold the fish-plates in position upon railroad-rails.

To this end the invention consists in a nutlock adapted for use upon nuts of different configurations, as hereinafter set forth.

The invention further contemplates means,

*substantially as hereinafter described, for securing the lock upon a nut and against accidental displacement therefrom; and it consists in the construction, arrangement, and combination of parts, substantially ashereinafter described, and specifically pointed out in the claims.

Figurel represents, in elevation, a section of a railroad-rail having {ish-plates held in position by bolts and nuts provided with my improvement. Fig. 2 is an end elevation thereof. Fig. 3 represents an enlarged detail view of my improved nut-lock, and Fig. 4 is an end elevation thereof.

Referring to the drawings, in which like letters of reference denote similar parts, A A designate abutting'seetions of railroad-rails; B, the fish-plates overlapping the joint between said rails and held in position by threaded bolts C, that pass through the rails A, fishplates B, and the nuts D, the latter engaging the screw-threads of the bolts and bearing against the outer face of the fish-plate.

As thus far described, the construction of parts is identical with that in common use in railroad engineering.

I Will now proceed to describe my improved nut-lock, its application to a nut, and the means whereby it is held against displacement.

E designates the complete nut-lock, consisting, essentially, of two bars or rods, e f, bent at suitable points to clasp the nuts and reversed and centrally hinged together.

For convenience, and to more clearly explain the construction of parts, I will describe but one of the rods,e, it being understood that the remaining rod, f, has similar form. Starting at the point or end e of the rod e, it projects downward toa point, e2, thence in a horizontal plane to the point e", thence upward to a-point, e", thence in upwardly-inclined direction to a point, e5, thence in an opposite inclined direction to a point, es, and thence downward to the opposite end of the rod.

By reference to the drawing Fig. 3 it will.

be seen that one side of the rod e between the points e and c4 will conform to and clasp the sides of asquare nut, and the oppositeside between the points e3 and e7 will conform to and clasp four sides of a hexagonal nut. Each end ofthe bar e is provided with a hook, es, to engage studs f8, formed upon each end of the bar f.

The bar or rod f, starting at the point f', is bent at pointsf2 f3 f, Sto., in a manner similar to the bar e.

In practice the bars are placed in reversed positionand hinged or pivoted together at g, the ends e f and eT and f7 in juxtaposition,

and the angle of one rod opposite like angles of the second rod.

When it is desired to apply the lock to a nut, the jaws are separated until they can be easily slipped upon said nut, when they are closed and the opposite ends of the rods secured together by the hook e8 and stud f8.

It will be apparent that the free portion of the lock beyond the side of the nut will rest upon the lower lianges, a, of the rail A, and thus effectually prevent the nut from turning upon its bolt.

From the foregoing description of my improved nut-lock it will be readily understood that nuts of different congurations and sizes may be locked.

Having thus described an embodiment of my invention, I would have it understood that changes can be made in the form and proportion of parts without departing from the spirit or sacrificing the advantages of my invention.
